table. On the inner end of this shaft is keyed the crank-plate M, to which is attached the pitman L. By means of the post attachments, consisting of sleeve box S, swivel box X> and sliding-boss Z> connection is so made between the pitman and the pump, that the revolving of the turn-table upon the bed plate will not twist or cramp the connections, or prevent sails being spread or furled, by means of shut-off rod R.

The regulating-gear consists of the sliding-head /?, elbows Y> and their connections. The inner end of each elbow is connected to the sliding-head by a link, the connections from the outer ends to the sails being made by means of regulating-rods.

On the outer ends of the regulating-rods are the governing-balls or regulating-weights, the action of which is the same as the governor on a steam-engine, causing the sails to present less surface to the wind as its velocity increases.

The weight W, on forked lever F, acts in opposition to the regulating-weights, causing the sails to present more surface to the wind as the power of the wind decreases. The sails may be furled, and the mill stopped and made to stand still, by pulling down on shut-off rod R. The regulating-gear is comparatively simple, securing a direct connection with each sail, and direct action of the regulating-weights on the sliding-head and its connections, thereby giving positive movement to all the parts.
